Ftp.proxy 1.2.3

ftp.proxy is an application level gateway for FTP. It sits between a client and a server forwarding command and data streams supporting a subset of the file transfer protocol as described in RFC 959.
But, beside this basic function which makes the program useful on firewall or masqueraders it offers fixing the FTP server (e.g. for connections into a protected LAN) and proxy authentication.
Main features:
- ftp.proxy offers external access control programs (ACP), that is an external program decides if a user can use the proxy service or not. This decision can be made on username, host name, day of time etc.
- Since version 1.0.1 ftp.proxy supports also command control programs. Similar to ACPs the CCPs permit or deny access to certain FTP commands on the server, e.g. its possible to allow a user to get files but to deny any kind of uploads.
